RPC Data Marshaling Functions

The functions in this section are Automation implementations of the ACF-type user_marshal attribute, which provides an efficient way to marshal custom data types that are unknown to MIDL.

In this section

Topic Description
BSTR_UserFree
Frees resources on the server side when called by RPC stub files.
BSTR_UserFree64
Frees resources on the server side when called by RPC stub files.
BSTR_UserMarshal
Marshals a BSTR object into the RPC buffer.
BSTR_UserMarshal64
Marshals a BSTR object into the RPC buffer.
BSTR_UserSize
Calculates the wire size of the BSTR object, and gets its handle and data.

LPSAFEARRAY_Marshal
Marshals a SAFEARRAY object to a user's RPC buffer on the server using information passed in by the LPSAFEARRAY_UserMarshal function.
LPSAFEARRAY_Size
Calculates the wire size of the SAFEARRAY object, and gets its handle and data needed by the LPSAFEARRAY_UserSize function.
LPSAFEARRAY_Unmarshal
Unmarshals a SAFEARRAY object from the RPC buffer using information passed in by the LPSAFEARRAY_UserUnmarshal function.
